RAILWAY TIE,

Specification of Letters Patent.

Patented Apr. 11, 1922.

Application filed June 21, 1921. Serial No. 479,301.

To all whom it may concern:

Be it known that I, Lorne S. PnUDHoMMn, a subject of the King of Great Britain, and resident of the city of St. Boniface, in the Province of Manitoba, Canada, have invented certain new anduseful Improvements in Railway Ties, of which the following is the specification.

The invention relates to improvements in railway ties and particularly to a rail tie and rail fastener and the object of the in vention is to provide an improved type of tie and a specially constructed fastening associated with the tie and adapted to hold the base of the rail, the said fastening being of simple and durable design and. arranged so that it can be readily installed and fas- 7 tened to hold the rail.

A further object is to construct a tie and fastening which when in use will positively prevent any possibility of the rails spreading and will firmly anchor the base of the rail in place.

WVith the above objects in View the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing in which Fig. 1 is a side View of a tie and fastening constructed in accordance with my invention and applied on the rail which is shown in vertical section.

Fig. 2 is a plan View of the parts appearing in Fig. 1, the fastening dogs being removed at the right hand end of the tie.

Fig. 3 is an enlarged vertical sectional view at 3-3 Figure 2.

Fig. 1 is an enlarged inverted plan view of one end of the tie.

Fig. 5 is a side view of the dog.

Fig. 6 is an inverted plan view of the dog.

Fig. 7 is a sectiona-l view showing a modified form of the tie in vertical section.

In the drawing like characters of reference indicate corresponding parts in the several figures.

In carrying out my invention I dispense entirely with the customary wooden ties or sleepers and mount the bases of the customary rails 1 and 2 on a metal tie 3 which is of channel iron cross section and is provided with cross channels 4 and 5 in the form of sunken chairs, the chairs or channels receiving the bases of the rails. Obviously the rail is prevented from side movement on the tie by the shoulders 6 and 7 formed by the sides of the channels. The

rails are both fastened to the tie in the same manner and as now described.

Centrally of the tie and at opposite sides of the rail base and somewhat back therefrom I make two square holes 8 and 9 and two slots 10 and 11 extending from a location adjacent the rail base to the inner sides of the openings 8 and 9.

By this arrangement I have really a pair of key hole slots in the tie at opposite sides of the rail base. To fasten the rail 1 provide a pair of similar dogs 12 and 13 and each dog is provided with a tapering end 1 1 adapted to fit the inclination of the top side of the rail base, a flat bottom 15 adapted to seat on the tie. a substantially square downwardly extending lug 16 and a more or less centrally positioned bolt opening 17 located between the lug 16 and the inclined end 14. the bolt opening having the lower end countersunk or coned as indicated at 18.

For each dog I provide a fastening bolt 19 adapted to pass through the opening 17 and fitted at one end. with a square head 20 and a tapering collar 21 spaced from the head by an intervening neck 22. The head 20 of the nut is adapted to pass through the opening 8 or 9 and the neck 22 to pass into the slot 10 or 11 and when the neck is in the slot the collar 21 overlies the edges of the slot. The length of the slot is such that the neck of the bolt will be stopped by the inner end of the slot when the outer side of the head. 20 is practically in the vertical. plane containing the inner side of the opening 8 or 9 or that side of the opening nearest the rail.

The tapered or coned. collar is adapted to fit the tapered end 18 of the opening 17 when the dog is applied on the bolt and the lug 16 of the dog in either case is adapted to pass into and fill the opening 8 and seat behind the head of the inserted bolt and so prevent the bolt from escaping outwardly. The head and collar of the bolt engaging with the sides of the slot will obviously prevent it from rising or lowering.

The dogs are fastened in place by nuts 23 screw threaded on to the upper ends of the bolts and tightened down against-the top faces of the dogs.

From the above description it will be apparent that it is an easy matter to fasten the rails where my tie and locking dogs are used as it is only a matter of inserting the bolts in the key hole slots, then placing the dogs on the bolts with the lugs behind the heads of the bolts and the tapering ends 14 overlying the rail base and finally tight-o ening the nuts 23 to complete the fastening. As the dogs are directly opposed at opposite sides of the rail base and overhang the same and the base of the rail is seated in the tie there is absolutely no possibility of the rail coming loose or spreading as very often occurs at the present time where spikes and such like are employed.

WVhere it is not desired to provide cross channels for the base of the rails in the tie I provide the modified arrangement as shown in Figure 7, where it will he observed that the tapering ends 14 of the dogs are provided with shoulders 24: and 25 which engage with the edges of the rail and prevent side movement of the rail. Obviously these latter shoulders take the place of the from the uppermost head, a rail base engag ing clip mounted onthe tie and formedwith a vertical bore receiving the threaded shank of the bolt therethrough, the lower end of the bore being enlarged to accommodate therein the upper head of the belt, a nut threadedlyengaged on the upper end of the threaded shank for holding said clip in po sition and a projection depending from the clip and fitting into the larger portion of the said slot.
